HOISTING AND DUMPING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 624,288, dated. May 2, 1899.

Application filed May 6, 1898. Serial No. 679,951. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. BOWERS, a citizen of the United States,residing at Salida, in the county of Chaffee and State of Colorado, have invented certain new and useful Improvements in Hoisting and Dumping Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hoisting and dumping apparatus; and the object of the invention is to provide an apparatus or device whereby a single workman may sink a well or shaft and remove the earth without having to climb up and down a ladder to empty his bucket or vessel which carries the dirt and rock.

The invention consists of the combination, with a suitable frame, of a Windlass or drum, a wheel connected with the drum adapted to be operated in either direction by means of an endless cord or rope which is adapted to be passed down into the .well or shaft over suitable pulleys or rollers, a trough or chute for discharging the earth away from the month of the shaft, an elevator-bucket connected with the Windlass-drum, a guide-roller arranged between the drum and the bucket to lead said bucket to and from the shaft or well, a tilting frame connected with the main frame, carrying the guide pulley or roller, a

' hoop or band connected with the bucket for engaging the tilting frame to tilt or dump the bucket, and means connected with the windlass-drum for returning the tilting frame to normal position upon reversal of the Windlass to lower the bucket into the well or shaft.

In the drawings forming a part of this specification, Figure 1 is a perspective showing my improved apparatus as applied to use in the sinking of a well or shaft, the bucket being in position ready to be lowered into the well or shaft. Fig. 2 is a section of my improved apparatus, showing the bucket raised out of the well and in the act of dumping or discharging its contents into the trough or chute. Fig. 3 is a top or plan view showing the parts in the same position that they are in Fig. 2. Fig. 4 is a detail showing the tilting frame detached.

1 1 are the'posts or uprights of the framework, made of lumber or other suitable material, and 2 2 are upper rails of the same.

3 is a trough or chute elevated at one end and inclined downwardly toward the other end in order to convey by gravity any sub stance which may be deposited therein. This chute or trough is arrangedabove the opening or top of the well or shaft 4, as is illustrated in the drawings. Mounted in the end of the frame away from the mouth of the well 4., is a Windlass-drum 5, which carries at one end of its shaft an operating grooved wheel 6, having a groove of sufiicient capacity to carry two or more turns of operating rope or cable. At the other end of the shaft of the drum is arranged a'gear wheel or pinion 7.

.8 is a tilting frame pivoted, as shown, to the trough and carrying at its forked or lower ends talons ,or hooks 1O 10. This tilting frame carries pulley 9 for guiding the hoisting-rope. The frame is preferablyformed of a single bar or piece of metal with bent or crooked side bars and an end bar, the extremities of the bar constituting the talons or hooks 1O 10. Mounted on the same pivots with the tilting frame 8 is another yoke or frame 11,

carrying at one end a vibrating lever 12. The yoke or frame 11 extends athwart or over that part of the swinging frame carrying the talons or hooks 10, so that when the frame Sis rocked upon its pivots the frame 11 will be carried or swung on the same pivot by it, and, as will be hereinafter described, the frame 8 is itself returned to normal position by means of the frame 11, operated through vibrating lever 12.

13 is an elevator-bucket provided with the usual bail, which is connected with the windlass rope or cable 14, leading from the bail of the bucket over guide-pulley 9 to Windlassdrum 5. The bucket is provided with a hoop or band 15, supported at some distance from its circumference by means of suitable brackets, as shown.

16 and 17 represent the opposite ends or parts of the rope or cord for operating the Windlass. This rope is wound once and a half or more times around the grooved wheel 6, and its opposite ends are led over guidepulleys 18 down into the well. By pulling on the part 16 of the operating-rope the bucket 13 is raised until the hoop or band 15 comes in range of the talons or hooks 10, when the tilting frame 8' is vibrated and carries the bucket over into the position shown in Figs. 2 and 3, and the contents of the bucket is dumped into the trough or chute 3, whence it is conveyed away by gravity from the mouth of the shaft. Operative] y connected with the spur gear-wheel 7 is a toothed rack-bar 19,

carrying at one extremity a fork 20, adapted to engage with the vibrating lever 12 when the frame 8 and yoke 11 have been tilted or carried into the position shown in Figs. 2 and 3. By pulling the part 17 of the operatingrope the direction of the Windlass is reversed, slack is given out to hoisting-rope 14:, the pinion 7 operates the rack-bar 19, and fork 20, engaging the lever 12, rocks the yoke 11, and through it tilting frame 8 is thrown back into the position shown in Fig. 1,and by continuing the movement the bncketis lowered into thewell, where it may be filled, after which the operator seizes thepart 16 of the operat- -ing-rope and repeats the operation.

The frame 8 is suitably stiffened by means of braces 21.

21 is a frame or extension connected. with the sides of the trough, and from this frame depend curved arms or projections 22, which serve as guides for the bucket to insure the engagement of the hoop on the bucket with the hooks 1O 10.

Having now described my invention, what eratingrcord leading into the shaft or well for operating the Windlass-drum in either direction, substantially as described.

2. The combination of an elevator-bucket provided with a hoop or bandas described, a hoisting rope or cable connected with said bucket, a tilting frame provided with talons or hooks adapted to engage the hoop or band on the bucket, a guide-pulley mounted on the tilting frame, means for operating the hoisting rope or cable to raise the bucket and tilt the frame, and means for reversing the movement and throwing the tilting frame back to normal position, substantially as described.

3. The combination of a bucket, a hoisting rope or cable connected with the bucket, a tilting frame, a guide-pulley connected with the tilting frame, means for interlocking the bucket and the tilting frame as the same is elevated, and means extending from the well or shaft to the Windlass for operating the hoisting rope or cable in either direction, substantially as described.

4. In hoisting apparatus, the combination of a .windlass, an elevator-bucket, a hoistingcable leading from Windlass to bucket, a tilting frame, a guide-pulley for the hoistingcable mounted on the tilting frame, a movable yoke or frame, means for operating the Windlass in either direction, and means connected with the Windlass for returning the tilting frame to normal position, substantially as described.

5. .Inhoist-ing apparatus, the combination of a hoisting-bucket, a hoisting-rope connected with 'the bucket, a guide-pulley for directing the bucket into and out of the well or shaft, a vibrating frame with which the guide-pulley is connected, a trough or chute, a drum for taking up and giving out the hoisting-rope, means for operating the drum from within the well or shaft, a reciprocating fork operated through the drum-shaft, and a movable yoke for operating the tilting frame as the Windlass is reversed. for lowering the bucket, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE H. BOVVERS.
